ABSTRACT:
A communication breaking device for breaking communication of an apparatus which communicates by modulation and demodulation using a predetermined code sequence. The predetermined code sequence is extracted from an incoming wave and an inverted-code generator inverts the code sequence into an inverted code sequence, which is transmitted as a communication breaking wave. The phase of the inverted code sequence is advanced before transmitting as the communication breaking wave and the pilot signal, can appropriately be compensated with the advanced inverted code sequence. It can be recognized by a portable telephone that the portable telephone is deviated from a communication area for the base station. A method includes compensating the code sequence in an incoming wave by transmitting a communication breaking wave.
